Okay my tank consist of mostly SPS frags and and fish. My pars have been spot on for a few months already thanks to the litermeter(Which doses Alk and Calcium only)... My Alk is 7.7-8.2 with Lamont Cal is 425-450 Elos and Mag was 1300 ppm with Sailfert test kit. i recently had some stn from lowering my nutrients to quickly but I fixed that with some fragging, water changes and adding reefbooster. I still don't have good growth ( i run Radiums) and color could be better. I didn't understand because I dose Cal and Alk with the dosing pump so I'm pretty consistent but I never had to dose Mag just added it with my water change (Tropin Marin) and it was aways at 1275 -1300 with Sailfert. Well I decided to try Elos mag kit and after doing like 5 test my Mag is at 1000pm. Now I'm thinking the Sailfert kits have been wrong all the time and my Mg is really low causing a lack of growth and color and possible the stn problem from a few weeks ago. Can SPS corals survive in this type of enviroment and is anyone having the same problem when changing from Sailfert to Elos or other? I think I will buy a third brand and see where that measures. Man this is very frustrating. I ask myself why do I try to keep sps??? I hate hobby test kits!! Thanks for your help.
